The invention relates to the related technical field of automobile parts and discloses a buffer energy storage extension type automobile front bumper, comprising a limiting frame, wherein a fixed column is mounted in the limiting frame; a fixing block is installed in the middle of the fixing column; sliding blocks are slidably connected to the middles of the two ends of the fixing column; a limiting spring sleeves the outer side of the fixed column between the outer sides of the sliding blocks and the inner wall of the limiting frame; buffering rods are hinged to the middles of the sliding blocks; rotating rods are hinged to the upper ends of the buffering rods; the lower ends of the rotating rods are hinged to the middles of the upper ends of the fixing blocks through hinge shafts; limiting wheels are installed at the top ends of the buffering rods; and the upper ends of the limiting wheels are clamped in limiting grooves in the middles of the bottom ends of the buffering frames. According to the invention, the sliding blocks can slide along the fixed column and is matched with the buffering rods and the rotating rods, so that the first-stage buffer effect is achieved; and meanwhile, the guide block can slide left and right along the guide column and is matched with the connecting rods, so that the second-stage buffering effect is achieved, and the buffering and damping effectof the whole automobile front bumper is further improved.
本发明涉及汽车零部件相关技术领域,公开了一种缓冲蓄能外延式汽车前保险杠,包括限位框,限位框内部安装固定柱,固定柱中部安装固定块,所述固定柱两端中部滑动连接有滑动块,滑动块外侧与限位框内壁之间固定柱外侧套有限位弹簧,所述滑动块中部铰接有缓冲杆,缓冲杆上端铰接有转动杆,转动杆下端通过铰接轴铰接于固定块上端中部,缓冲杆顶端安装限位轮,限位轮上端卡接在设于缓冲框底端中部的限位槽内。本发明,通过将滑动块可以沿着固定柱进行滑动,并且与缓冲杆以及转动杆相互配合,实现了一级缓冲作用,同时通过将导向块可以沿着导向柱左右滑动,并且与连杆相互配合,实现了二级缓冲作用,进一步增加了整个汽车前保险杠的缓冲减震作用。
